Referring to FIG. 1, the electronic device 101 in the network environment 100 may communicate with an electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or at least one of an electronic device 104 or a server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connecting terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the components (e.g., the connecting terminal 178) may be omitted from the electronic device 101, or one or more other components may be added in the electronic device 101. In some embodiments, some of the components (e.g., the sensor module 176, the camera module 180, or the antenna module 197) may be implemented as a single component (e.g., the display module 160).

The processor 120 may execute, for example, software (e.g., a program 140) to control at least one other component (e.g., a hardware or software component) of the electronic device 101 coupled with the processor 120, and may perform various data processing or computation.

According to one embodiment, as at least part of the data processing or computation, the processor 120 may store a command or data received from another component (e.g., the sensor module 176 or the communication module 190) in volatile memory 132, process the command or the data stored in the volatile memory 132, and store resulting data in non-volatile memory 134.

According to an embodiment, the receiver may be implemented as separate from, or as part of the speaker.

The display module 160 may visually provide information to the outside (e.g., a user) of the electronic device 101. The display module 160 may include, for example, a display, a hologram device, or a projector and control circuitry to control a corresponding one of the display, hologram device, and projector. According to an embodiment, the display module 160 may include a touch sensor adapted to detect a touch, or a pressure sensor adapted to measure the intensity of force incurred by the touch.

The sensor module 176 may detect an operational state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a state of a user) external to the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state. According to an embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

The interface 177 may support one or more specified protocols to be used for the electronic device 101 to be coupled with the external electronic device (e.g., the electronic device 102) directly (e.g., wiredly) or wirelessly. According to an embodiment, the interface 177 may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface.

A connecting terminal 178 may include a connector via which the electronic device 101 may be physically connected with the external electronic device (e.g., the electronic device 102). According to an embodiment, the connecting terminal 178 may include, for example, a HDMI connector, a USB connector, a SD card connector, or an audio connector (e.g., a headphone connector).

According to an embodiment, the haptic module 179 may include, for example, a motor, a piezoelectric element, or an electric stimulator.

The camera module 180 may capture a still image or moving images. According to an embodiment, the camera module 180 may include one or more lenses, image sensors, image signal processors, or flashes.

The power management module 188 may manage power supplied to the electronic device 101. According to one embodiment, the power management module 188 may be implemented as at least part of, for example, a power management integrated circuit (PMIC).

The battery 189 may supply power to at least one component of the electronic device 101. According to an embodiment, the battery 189 may include, for example, a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell.

The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module 192 may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module 192 may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module 192 may support various requirements specified in the electronic device 101, an external electronic device (e.g., the electronic device 104), or a network system (e.g., the second network 199). According to an embodiment, the wireless communication module 192 may support a peak data rate (e.g., 20 Gbps or more) for implementing eMBB, loss coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of downlink (DL) and uplink (UL), or a round trip of lms or less) for implementing URLLC.

The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. According to an embodiment, the antenna module 197 may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, the antenna module 197 may include a plurality of antennas (e.g., array antennas). In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

According to certain embodiments, the antenna module 197 may form a mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example.

In another embodiment, the external electronic device 104 may include an internet-of-things (IoT) device. The server 108 may be an intelligent server using machine learning and/or a neural network. According to an embodiment, the external electronic device 104 or the server 108 may be included in the second network 199. The electronic device 101 may be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology or IoT-related technology.

FIG. 2A is a front perspective view of an electronic device 200 in a closed state according to one embodiment. FIG. 2B is a rear perspective view of the electronic device 200 in a closed state according to one embodiment. FIG. 3A is a front perspective view of the electronic device 200 in an open state according to one embodiment. FIG. 3B is a rear perspective view of the electronic device 200 in an open state according to one embodiment.

According to certain embodiments, the electronic device 200 in FIG. 2A may include an electronic device 101 in FIG. 1.

Referring to FIGS. 2A, 2B, 3A, and 3B, the electronic device 200 in one embodiment may be implemented such that a screen 2301 thereof can be expanded in a sliding manner. For example, the screen 2301 may be an area of a flexible display 230, which is seen from the outside. FIGS. 2A and 2B illustrate the electronic device 200 in a state in which the screen 2301 is not expanded, and FIGS. 3A and 3B illustrate the electronic device 200 in a state in which the screen 2301 is expanded. The state in which the screen 2301 is not expanded may be a state in which a sliding plate 220 for sliding motion of the flexible display 230 is not slid out and may be hereinafter referred to as the “closed state”. The state in which the screen 2301 is expanded may be a maximally expanded state in which the screen 2301 is slid out by the sliding plate 220 as much as possible, and may be hereinafter referred to as the “open state.” Alternatively, the sliding plate 220 may partially move in a first direction (e.g., +x-axis direction) when the electronic device 200 is transitioned from the closed state to the open state. According to certain embodiments, in comparison with the closed state, the open state or a partially open state may be defined as states in which the screen 2301 is expanded, and may provide screens of various sizes according to the position at which the sliding plate 220 has moved. According to certain embodiments, an intermediate state may refer to a state between the closed state in FIG. 2A and the open state in FIG. 3A. The screen 2301 may include an active area of the flexible display 230 that is visually exposed so as to enable an image to be output, and the electronic device 200 may adjust the active area according to the movement of the sliding plate 220 or the movement of the flexible display 230. In the following description, the open state may refer to a state in which the screen 2301 is expanded to the maximum. In an embodiment, the flexible display 230 disposed to be slidably movable on the electronic device 200 in FIG. 2A to provide the screen 2301 may be referred to as a “slide-out display” or “expandable display.” In one embodiment, the sliding structure related to the flexible display 230 of the electronic device 200 may include a free-stop structure. For example, when the flexible display 230 is moved by an external force, due to the free-stop structure included in the sliding structure, the electronic device 200 may move the flexible display 230 only by the distance caused by the external force.

According to certain embodiments, the electronic device 200 may include a sliding structure related to the flexible display 230. For example, when the flexible display 230 is moved to a predetermined distance by an external force, due to an elastic structure included in the sliding structure, the flexible display 230 may be transitioned from the closed state to the open state or from the open state to the closed state without any further external force (e.g., semi-automatic slide motion). According to an embodiment, when a signal is generated through an input device included in the electronic device 200, the electronic device 200 may be transitioned from the closed state to the open state or from the open state to the closed state due to a driving device such as a motor connected to the flexible display 230. For example, when a signal is generated through a hardware button or a software button provided through a screen, the electronic device 200 may be transitioned from the closed state to the open state or from the open state to the closed state.

According to certain embodiments, when signals are generated from various sensors such as a pressure sensor, the electronic device 200 may be transitioned from the closed state to the open state or from the open state to the closed state. For example, when the electronic device 200 is carried or grasped by a hand of a user, a squeeze gesture in which a portion of the hand (e.g., palm or finger) presses a predetermined portion of the electronic device 200 may be detected by the sensor, and in response thereto, the electronic device 200 may be transitioned from the closed state to the open state or from the open state to the closed state.

According to one embodiment, the display 230 may include a second section {circle around (2)} (see FIG. 3A). The second section {circle around (2)} may include an expanded portion of the screen 2301 when the electronic device 200 is transitioned from the closed state to the open state. When the electronic device 200 is transitioned from the closed state to the open state, the second section (0) may be slid out from the inner space of the electronic device 200, and thus the screen 2301 may increase in area. When the electronic device 200 is transitioned from the open state to the closed state, at least a portion of the second section ({circle around (2)}) may be drawn back into the inner space of the electronic device 200 in a sliding manner, and thus the screen 2301 may be reduced in area. When the electronic device 200 is transitioned from the open state to the closed state, at least a portion of the second section {circle around (2)} may be bent and moved into the inner space of the electronic device 200. For example, the flexible display 230 may include a flexible substrate (e.g., plastic substrate) made of a polymer material such as polyimide (PI) or polyester (PET). The second section {circle around (2)} is a portion of the flexible display 230 that may be bent when the electronic device 200 is transitioned between the open state and the closed state, and may also be referred to as, for example, the bendable section of the flexible display. In the following description, the second section ({circle around (2)}) will be referred to as the bendable section.

According to one embodiment, the electronic device 200 may include a housing 210, the sliding plate 220, and/or the flexible display 230.

The housing (or case) 210 may include, for example, a back cover 212, a first side cover 213, or a second side cover 214. The back cover 212, the first side cover 213, or the second side cover 214 may be connected to a support member (not shown) located inside the electronic device 200, and may define at least a portion of the external appearance of the electronic device 200.

The back cover 212 may include, for example, at least a portion of the rear surface 200B of the electronic device 200. In one embodiment, the back cover 212 may be substantially opaque. For example, the back cover 212 may be made of coated or colored glass, ceramic, polymer, or metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the above materials. According to an embodiment, in a state in which the bendable section {circle around (2)} of the flexible display 230 is drawn into the inner space of the housing 210 (e.g., closed state), at least a portion of the bendable section {circle around (2)} may also be disposed to be visible from the outside through the back cover 212. In this case, the back cover 212 may be made of a transparent material and/or a translucent material.

According to one embodiment, the back cover 212 may include a flat portion 212 a and curved portions 212 b and 212 c positioned opposite to each other with the flat portion 212 a interposed therebetween. The curved portions 212 b and 212 c may be formed adjacent to the longitudinal edges (not shown) of the back cover 212, respectively, and may be curved and seamlessly extend toward the screen located on the front of the electronic device 200. According to an embodiment, the back cover 212 may include one of the curved portions 212 b and 212 c or may be implemented without the curved portions 212 b and 212 c.

According to one embodiment, the first side cover 213 and the second side cover 214 may be positioned opposite to each other. For example, the first side cover 213 and the second side cover 214 may be positioned opposite to each other in a second direction (e.g., y-axis direction) perpendicular to the first direction (e.g., +x-axis direction) of the sliding movement of the sliding plate 220, with the flexible display 230 interposed therebetween. The first side cover 213 may form at least a portion of the first side surface 213 a of the electronic device 200, and the second side cover 214 may form at least a portion of a second side surface 214 a of the electronic device 200, facing in a direction opposite the first side surface 213 a. The first side cover 213 may include a first edge portion (or first rim) 213 b extending from the edge of the first side surface 213 a. For example, the first edge portion 213 b may form at least a portion of a bezel at one side of the electronic device 200. The second side cover 214 may include a second edge portion (or second rim) 214 b extending from the edge of the second side surface 214 a. For example, the second edge portion 214 b may form at least a portion of the bezel at the other side of the electronic device 200. According to one embodiment, the surface of the first edge portion 213 b, the surface of the second edge portion 214 b, and the surface of the sliding plate 220 may be smoothly connected in the closed state as shown in FIG. 2A and may thus form a curved portion on one side thereof, corresponding to the first curved portion 230 b of the screen 2301. According to certain embodiments, the surface of the first edge portion 213 b or the surface of the second edge portion 214 b may include a curved portion on the other side thereof, corresponding to the second curved portion 230 c of the screen 2301, which is positioned opposite to the first curved portion 230b.

According to one embodiment, the sliding plate 220 may slide on a support member (not shown) located inside the electronic device 200. At least a portion of the flexible display 230 may be disposed on the sliding plate 220, and the closed state of FIG. 2A or the open state of FIG. 3A may be realized based on a position of the sliding plate 220 on the support member. According to one embodiment, the flexible display 230 may be attached to the sliding plate 220 through an adhesive member (not shown). According to one embodiment, the adhesive member may include a heat-reactive adhesive member, a photoreactive adhesive member, a general adhesive, and/or a double-sided tape. According to an embodiment, the flexible display 230 may be slidably inserted into a recess formed on the sliding plate 220 so that it is fixed onto the sliding plate 220. The sliding plate 220 may serve to support at least a portion of the flexible display 230 and may be referred to as a display support structure herein.

According to one embodiment, the sliding plate 220 may include a third edge portion 220 b forming an outer surface (e.g., surface exposed to the outside to define the external appearance of the electronic device 200) of the electronic device 200. For example, in the closed state of FIG. 2A, the third edge portion 220 b may form the bezel around the screen together with the first edge portion 213 b and the second edge portion 214 b. In the closed state, the third edge portion 220 b may extend in the second direction (e.g., y-axis direction) to connect one end of the first side cover 213 to one end of the second side cover 214. For example, in the closed state of FIG. 2A, the surface of the third edge portion 220 b may be smoothly connected to the surface of the first edge portion 213 b and/or the surface of the second edge portion 214 b.

According to one embodiment, due to the slide-out of the sliding plate 220, at least a portion of the bendable section {circle around (2)} may come out from the inside of the electronic device 200, and accordingly, the state in which the screen 2301 is expanded (e.g., open state) may be provided as shown in FIG. 3A.
